Binder composition and coating composition for decorative paper both based on polyurethane resin, and laminated cloth and air bag both having coating of the same

Abstract

A polyurethane resin obtained from a diisocyanate compound and a polyester polyol. The polyester polyol may (1) comprise not less than 50% by weight of a polyester glycol having a molecular weight of 500-5,000, the polyester glycol being obtained by reacting an acid and 3,3,5-trimethyl-1,6-hexanediol or 2,2,4-trimethyl-1,6-hexanediol and have a molecular weight of 500-5,000, (2) have a number average molecular weight of 500-5,000 and an alcohol hydroxyl group at terminals thereof and comprise not less than 50% by weight of ester units, the ester units being derived from a dicarboxylic acid and 3,3,5-trimethyl-1,6-hexanediol and/or 2,2,4-trimethyl-1,6-hexanediol, or (3) have a number-average molecular weight of 500-5,000 and comprise not less than 50% by weight of ester units of an aliphatic dicarboxylic acid and trimethyl-1,6-hexanediols. The above polyurethane resins may be combined with chlorinated polyolefin and then used in binder compositions or, alternately used in coating compositions for decoration paper made of a polyolefin resin. The above polyurethane resins may also be laminated on at least one surface of a woven cloth made of synthetic resin to form a laminated clothing that may further be used in an air bag for a vehicle.
